After making your own way to Casa de les Punxes, located on Av. Diagonal nearby the metro station of the same name, present your voucher to a cashier in exchange for an audiovisual guide.
Head straight to the first floor, where you’ll learn of Sant Jordi’s importance in the modernist movement while admiring the elaborate art nouveau décor of the rooms: marvel at prismatic stained glass windows, ironwork, and surrealist paintings.
Then, take an elevator to Casa de les Punxes’ crowning glory: the roof terrace. Note the contrasting themes of each tower, decorated according to different social movements, before descending to the gift shop to purchase unique souvenirs.
